Abstract: MULTIMODE OPTICAL FIBER Abstract of the Disclosure A multimode optical fiber waveguide with graded refractive index for lessening modal dispersion with the gradient produced at least in part by radially decreasing boron oxide content outwardly from the core center within a high silica glass core minimizes modal dispersion by use of a non-parabolic grading function.  The optimum gradient for a simple binary borosilicate system for a wavelength of from approximately 0.5 to 1.1 micrometers corresponds with .alpha. = 1.77 ? 10 percent in the equation n = n1[1-2.DELTA.(r/a).alpha.]1/2, in which n1 is the axial core index r is the distance from the fiber axis, a is the core radius, .DELTA. is the relative index difference between core center and cladding and .alpha. is a power law exponent which characterizes the profile.

Abstract: ABSTRACT:            An electrode structure within the cavity of an acoustic surface wave resonator, e.g. an interdigital transducer or a multistrip coupler, has two sections separated by an odd integral multiple of a quarter wavelength of the standing wave in the cavity and located with respect to the centre of the cavity so that all the electrodes are midway between a node and an adjacent antinode of the standing wave. Distortion of the resonator response due to reflection by the electrodes of the transducer or coupler is suppressed by this arrangement.

Abstract: ABSTRACT OF THE DISCLOSURE           A method and apparatus for the control of gaseous and volatile combustibles in a cellulose pulp delignifying and bleach-ing oxygen reactor to maintain the concentration of combustibles below explosive levels.  A fan withdraws gaseous and volatile combustibles mixed with oxygen from the top of a conventional oxygen reactor, and passes at least a portion of the withdrawn gases through a combustion chamber having hot catalytic wires or the like disposed therein.  Thorough mixing of the gases may be effected before they are brought into contact with the catalytic wires. The combustible components of the gases in the combustion chamber are combusted, and the gases exiting from the combustion chamber are cooled and then returned to the oxygen reactor.  A bypass line in fluid circuit parallel with the combustion chamber is provided, and an adjustable bypass valve is disposed in the bypass line.  The adjustment of the bypass valve controls the amount of gas flowing through the combustion chamber and the amount flowing directly back to the reactor.  Cooling means may also be provided in the bypass line and the temperature in the r actor controlled thereby.

Abstract: ABSTRACT OF THE DISCLOSURE     A hose connector of the plug-and-socket type including a clamp comprised of at least two jointed shell members having axially spaced and radially inwardly turned end flanges.  One of the flanges engages the plug section of the connector such as to receive inwardly of the respective flange a radial collar provided on the periphery of the plug member.  The other of the flanges engages the periphery of a hose end pulled over a nozzle extension of the socket portion, to push the hose into a radial recess in the outside periphery of the nozzle extension.  Thus, the clamp simultaneously prevents axial displacement of the connector and secures the hose to said nozzle end section by a radially inwardly directed force.

Abstract: AUXILIARY POWER SYSTEM AND APPARATUS             Abstract of the Disclosure An auxiliary power system for an internal combustion engine. The system employs a vapor or hot gas engine coupled to an internal combustion engine by means of an overrunning clutch assembly.  The internal combustion engine, operated conventionally, generates heat in its cooling and exhaust systems as well as in accessory equipment.  The heat generated in the internal combustion engine and its accessories is used for generating vapor in one or more heat exchangers, the vapor preferably being from a liquid with a boiling point well below that of water.  The generated vapor is used to drive a vapor engine.  Temperature-sensitive means is employed to measure the heat generated in one or more parts of the system for controlling a linear solenoid valve. for automatically control-ling the internal combustion engine temperatures and thereby the amount of vapor generated.  A vacuum-controlled throttle valve is also employed in conjunction with the solenoid-operated valve for automatically controlling the input of vapor to the vapor engine for controlling its idle speed and for providing maximum acceleration as needed.  Safety valve means and vapor condensing means are provided at the output of the heat exchangers and steam engine to condense the generated vapor for recirculation in the system.

Abstract: ABSTRACT         Method, apparatus and system for sorting objects exhi-biting identifiable dynamic response to vibrational phenomena, such objects including tomatoes and other comestibles.  The sys-tem utilizes an elongate sorting zone incorporating a surface which oscillates at a predetermined frequency and amplitude which varies from a minimum at the input of the zone to a maximum value at the output thereof.  Conveyor belts transport the objects to be sorted along the zone for a coding interval promoting their dynamic reaction with the oscillatory surface.  Objects with higher resilience characteristic are rejected from the zone, while those exhibiting a lesser resilience are transported there-through.  The oscillatory surface is dynamically balanced and readily mounted upon field harvesting devices.  By adjustment of frequency of the sorting zone oscillatory surfaces, a multi-stage sorting system is made available.
